Maniac is a 1980 American psychological slasher film directed by William Lustig and written by C. A. Rosenberg and Joe Spinell. It stars Spinell as Frank Zito, an Italian-American serial killer residing in New York City who murders and scalps young women.

With a minuscule budget, many scenes in the film were shot guerrilla style. Originally considered an exploitation film, Maniac has since attained a cult following despite receiving polarized reviews. The film was remade in 2012 by director Franck Khalfoun and produced by Alexandre Aja, starring Elijah Wood in the lead role.

While not prosecuted for obscenity nor officially listed as a video nasty, Maniac was seized by various police forces across Greater Manchester and Lancashire in England during the video nasty panic, presumably based on the film's notorious reputation overseas.

Plot Italian-American landlord Frank Zito was abused as a child by his prostitute mother Carmen, and as a result, becomes a serial killer who murders young women, scalps them and attaches their hair to mannequins. After he awakens from a nightmare about killing a couple on a beach, he dresses himself, revealing terrible scars on his torso, and leaves his apartment, heading towards Manhattan into Times Square. When Frank is randomly invited inside a hotel by a prostitute, she kisses him before he abruptly strangles and scalps her. He returns home, dresses a mannequin with the dead prostitute's clothing and nails her scalp to its head. Frank tells himself that beauty is a crime punishable by death.

Sometime later, he dresses again and takes a collection of weaponry with him, including a double-barrelled shotgun, before leaving. He drives around Brooklyn and the Queens area, where he finds a couple exiting a local disco and parking near the side of the Verrazzano Bridge. When the boyfriend starts up the vehicle after his date sees Frank spying on them, Frank kills the couple with his shotgun and then adds the woman to his mannequin collection. After seeing his recent crime on television, he talks to himself and the mannequins as he sobs himself to sleep.

During the next day in Central Park, Frank follows a photographer named Anna after she takes a photo of him and a little girl riding a bicycle in the distance. At night, Frank sees a nurse leaving the Roosevelt Hospital, where he then stalks her inside the subway station and murders her with a bayonet before adding her to his mannequin collection. Days later, Frank heads to Anna's apartment and is invited inside by Anna after she recognizes him from the photo she took of him. Upon him asking her out to dinner, he later shows her a photo of his mother who died in a car crash years ago. A few days later, Frank is invited by Anna to a studio during a photography session, and she introduces one of her models Rita to him. After seeing the two talking and holding hands, he steals Rita's necklace and leaves. Later that same night, he arrives at Rita's apartment to give her the necklace, before then attacking her and tying her to the bed. Frank begins talking and addresses her as his mother and stabs her with a switchblade before scalping her for his collection.

One night, Frank takes Anna on a date and they stop by a cemetery to visit his mother's grave. While laying some flowers beside the headstone, Frank begins to mourn over his mother as well as Rita and attacks Anna. He chases her around the cemetery, but she hits him in the arm with a shovel before fleeing. He hallucinates his decomposing mother attacking him from the grave. He runs back to his apartment, where he sees his mannequins suddenly coming alive. They mutilate Frank with his weapons before ultimately tearing off his head.

The next morning, two police officers break into Frank's apartment and see Frank lying dead on his bed, having committed suicide by stabbing himself. After the officers leave, Frank's eyes suddenly open, revealing he survived.

Cast

Production Development Director William Lustig, who previously had worked as a director of pornographic films, was driving with Frank Pesce down the Eighth Avenue one night. Pesce asked Lustig if he could make a film similar to Jaws, but "on land". Lustig and co-writer Joe Spinell (whom he had met while working on The Seven-Ups) developed the script for an unreleased film named Slay Ride, about a father-son serial killer duo in New Jersey. They found that Slay Ride was "a much bigger film that [they] could raise money for", and decided to make a "smaller, more contained" film, titled Maniac. They came up with the idea of "[a] monster that was inside of [a] person, [who] had this insatiable appetite for killing that just kept driving him".Heather Wixson, "45 Years Later: Celebrating William Lustig's Maniac", THC, July 14, 2025. The film's original script was to follow a cop chasing a serial killer in New York City, but this was changed to instead focus on the killer. Lustig felt that this decision "made for a much better movie" as it eliminated the "relief of going to a place of safety". Lustig used profits from his 1977 film Hot Honey to make the film, with co-producer Andrew W. Garroni and Spinell also contributing.

At the time, Screen Actors Guild contracts contained a clause that excluded X-rated films from union oversight. Lustig anticipated that Maniac would receive an X rating due to its gore effects, similar to Dawn of the Deads initial rating, and submitted the script to SAG for review. When the initial submission was not rejected, Lustig submitted a revised script containing intentionally exaggerated, explicit depictions of violence and gore. SAG formally rejected this script, assuming that the final film would receive an X rating.Maniac DVD commentary by William Lustig and Tom Savini.

Casting Because Maniac did not have the budget to secure a contract with SAG and the script was rejected, Lustig used a loophole to cast SAG actors, including Spinell, without exposing them to union penalties. Spinell wanted to play Frank Zito, and researched real-life serial killers such as Ted Bundy, John Wayne Gacy, Henry Lee Lucas, Ed Gein, and David Berkowitz to get into the role. He also saw a young child rocking by himself outside Lustig's apartment, which he incorporated into Frank's character, and came up with the idea that Frank would have scars from his abuse by his mother Carmen Zito. At one point during production, Spinell shaved his mustache and cut his hair to portray Lieutenant Munafo in Nighthawks. He wore a long-haired wig and fake mustache for the remaining scenes. Dario Argento's wife Daria Nicolodi was considered for the role of Anna D'Antoni, but was unavailable at the time since she was filming Inferno in Italy. Judd Hamilton provided the money to finish the film on the condition that his then-wife Caroline Munro be cast instead. Maniac was one of the three films that Spinell and Munro worked together; the other films being Starcrash and later The Last Horror Film. Munro's casting led to an increase in screentime for Anna, including particular scenes where she and Frank get to know each other and go on dates, which Lustig disliked. Several pornographic film actresses were hired to play Frank's victims and other minor female roles. Susan Tyrrell and Jason Miller were cast for the film, with Miller playing the cop from the film's original script, but they dropped out for unknown reasons.

Lustig played a hotel manager, during which Spinell kept trying to make him crack on camera by writing jokes on the check-in card. Frank Pesce provided the voice of a television reporter. Tom Savini and his real-life girlfriend Hyla Marrow made cameo appearances as the boyfriend and girlfriend killed by Frank. Louis Jawitz, who played Anna's art director, was actually a professional photographer who leased his studio to be used for one day to shoot the scene in which Frank visits Anna and three female models in the studio.

Filming Principal photography began on October 21, 1979, and wrapped on January 18, 1980. The film was shot on location in New York City on a $48,000 budget in 26 days. Many scenes had to be filmed guerrilla-style because the production could not afford city permits. Lorenzo Marinelli was hired to edit the film. The opening scene on the beach was shot as a homage to Jaws. The exterior of the hotel in the scene where Frank is invited inside by a prostitute was filmed at the St. James Hotel, during which they were approached by police looking for a serial killer. Lustig stated that on the night after they were at the hotel, the crew read news that a woman had been decapitated there. Two other women had also been murdered in the Travel Inn Hotel in Times Square at the time, and police dressed up mannequins in the victims' clothes to identify them, similar to Frank dressing his mannequins with his victims' clothes and hair in the film.

Tom Savini was hired as the film's make-up artist while working on Friday the 13th, feeling upset that his work on the latter film was being cut. The sound effect for Frank ripping the prostitute's flesh when scalping her was created by twisting a leather wallet near a microphone. The scene where Frank murders the boyfriend (played by Savini) was filmed near the Verrazzano–Narrows Bridge in an hour, and loosely inspired by the "Son of Sam" murders committed by David Berkowitz, who shot people in parked cars with a .44 Special revolver. Savini received the role for the male victim from him having already made a cast of his own head, which was filled inside with leftover food, pig intestines, and fake blood. Since Savini used live ammunition for the scene, with the force of the blast making him fall off the car's hood, he immediately threw the shotgun into the trunk of a waiting car driven by Spinell's friend and assistant Luke Walter, to avoid being caught by the police. The part where Frank murders the female victim (played by Hyla Marrow) was filmed in a different location at a later date. The dummy was locked in the trunk of the car used in the scene. Because the car had begun to smell because of the pig intestines, it was then sunk to the bottom of the East River. The sound effect for the shotgun being fired was reused from Dawn of the Dead.

The scene with the helicopter POV shot was repurposed from an unused scene for Inferno. According to Lustig, Frank's apartment was designed by an unknown individual, who built an actual apartment with immovable walls and running water. Spinell and the designer furnished the apartment with props, dolls and mannequins. Savini also reused the headless corpse of Pamela Voorhees from Friday the 13th for the scene in which Frank is killed by his mannequins.

Soundtrack Lustig considered hiring the Italian progressive rock band Goblin to compose the soundtrack for Maniac, as Dario Argento had used them for his horror films, but decided to use Jay Chattaway instead.

Release According to Variety report, Maniac was scheduled for a midnight screening at the Cannes Film Festival on May 10, 1980. The film had its U.S. premiere in New York City on January 30, 1981, followed by a Los Angeles premiere on March 6.

Censorship Since the film was not submitted to the MPAA, the film was released unrated, with the designation "For adults only". Despite the poster stating "No one under 17 will be admitted", a severely-edited version of the film received an R-Rating in the South and was distributed in March 1981 in several other States such as California, of the unrated version shortly after its first U.S. domestic release in New York in January 1981.

The film was refused a classification by the British Board of Film Classification upon its original cinema release and was additionally banned for video in 1998, but was later passed at an 18 certificate in 2002 with 58 seconds of cuts. In 2022, the BBFC passed the film uncut with an 18 certificate.
